Tins-RIM.

Patented Nov. 18, 1919.

Application filed June 19, 1918. Serial No. 240,751.

To all whom it may concern The object .of my invention is to provide a flanged rim which can readilyand easily be, in efi'ect, contracted in circumference and diameter, so that it can be entered into and taken from a tire casing or tire which is adapted to be mounted thereon. As now constructed, it is well known'that many pile-lunatic tires and solid tires have bases or base beads which are substantially in extensible. The rims which carry such tires are provided with base engagingv flanges, and it is therefore'necessaryto split the rim at one or more points in order to be able to enterthe rim into the tire or to re move it therefrom.

My invention consists in a tire rim cut into two or more sections, one of which sections is relatively short and which is easily removable from a position between the ends of the other part of the. rim where it braces the ends of the other part apart and forms a true circular rim of the proper dimensions, to a position within the circle of the rim where it permits the ends of the other part to approach eachother and thus lessen the curvature of the rim sufficiently so that the flanges of the rim are withdrawn inwardly to permit the rim to pass readily through the tire into and out of tire receiv in position.

h Iy invention also consists in the several features of construction and in thearrangements and combinations of parts by which. i am enabled to attain theabove mentioned and other objects, and all as hereinafter described and particularly pointed out in the ap ended claims.

y invention will be more readily understood by reference to the accompanying drawings forming part of this specification,

and in which- Figure 1 is a side elevation ot a rim constructed 1n accordance with my invention and shown in extended or tire holding condition; 1

Fig. 2 is a fragmentary sectional view showing a rim in collapsed or tire removable condition; v

Fig. 3 is a fragmentary inner plan view pt 1: portion of the rim showing the toggle Fig. 4 is a fragmentary outer plan View of the linked ends of the rim;

Fig. 5 1s a smnlar plan view of the spring oint of the rim; and

.Fig. 6 1s a fragmentary perspective plan view "of one of the radially interlocking rim joints.

y In said drawings, '1 is a rim having circnmferential flanges 2 for receiving the base or base beads of the tire. The rim is channel shaped in cross section, it may be of the ciencher or straight flange type.

In order to collapse the rim I cut it into three parts or sections 3, 4 and 5. Proton ably the sections 3 and at are of equal length, and together make' up about three quarters of the circumference of the rim. The section 5 is shorter than the others, making up about one quarter of the circumference of the rim.

These three sections or parts when arranged'as shown in Fig. 1, that is, in end to and relation, form a rim of the proper circumference and diameter to hold a tire of cooperating dimensions.

I preferably connect the sections 3 and 4 together at their adjacent ends by a strap 6 of spring metal, such as steel, riveting the ends of the strap to the web of the rim by the rivets 7, preferably two at each end.

The two rivets at each end are arranged transversely so as best to hold the sections in alinement. In order to take the radial strain on of the strap (5, I cut or form the ends of the sections with radially contacting sl'loulders 8 and 9 respectively. In other words, I cut the flanges 2 at the joint on zigzag lines as shown to provide a recess 10 on one end and a cooperating tongue 11 on the other end, making the tongues on the opposite sides of the rim extend in opposite directions so as best to dowel or interlock the ends against relative radial movement.

Between the section 4c and the section 5 I provide a hinged joint' of limited movement. That is, I provide a joint which per ell) the ed;

eatent to peri'nit shown in Fig. The hinge olnt consists of a rigid plate loosely jointed to the adjacent ends of the sections 4: and 5 by spherically headed rivets 18. The outer surface oi the plate 12 is formed. on a curwators of smaller radius than the inner snrface of the rim against which it contacts and the rivets 13 are long enough to permit the ends of the plate to separate from the rim. when. the rim is in expanded position and to permit the relative radial movement of the of the plate and rim as the section 5 swings into its inner or collapsed. position.

1 preferably form this cut in the rim also with the double interlocking tongues, simi lar to the joint between the sections 8 and 4t.

For thepurpose of joining the adjacent ends of the sections 3 and 5 to permit the collapsing movement of the section 5, 1 pro-- ride a toggle linlt 1-1- formed. of strap metal and I permanently hinge the ends of this linlt to the adjacent ends of the sections 3 and Preferably ll arrange the hinge joint 15 hetWeent e-link and the section 5 beyond the end the section 5 to permit the relative movement of the section 5 desired, and l: arrange the hinge connection lG-hetween the link: l-l and the section 3 at a suitable distance haclt from the end of the section 3 so that the rim will be expanded by the linlr to proper tire holding condition with. "acent ends of the sections 3 and in prope contact with. each other.

l to 11 one end of the plate 14. into a part the hinge 15., and 1 form the cooperating part of the hinge on the project ing end of a connection plate 17 which I rivet to the section-5, and. the two parts of the hinge are pivotally joined by the hinge pin 18.

To provide the hinge joint 16, I preferahly to m. two parallel projections 19 on the end of the linl: 14., each provided with a hall-like formation 20 on its end, and I proride sockets no receive the balls 20 in a l hold the halls in the sockets 21 by means of 'a second plate 23 which overlies the plate 22, the. tivrrplatcs being secured together and upon the rim by the rivets 24-.

The plate is slotted to receive the projections l9, and the platl: is provided "with slots 25 to permit the link 14 to swing out when the rim collapsed. The sockets for the balls :20 may he partly formed in the I provide the adjacent ends of the rim marines each other and thus shorten the rim, as a Whole 7 If this does not suilice to pern'nt the removal of the run from the tire, it is oh- I vious that by applying pressure outwaiidly upon the linked end oi the section 5, the llnk' will sw ng farther upon the pin. 18 and ii ll the rim will he forcibly made smaller, the

sections 3 and l moving toward each other upon the spring plate 6 as upon a hinge.

Having collapsed the rim it can he read ily entered into a tire and then readily expanded to tire engaglng and holding condition by reversing the action clec-ribcd." The section swings easil hack to'its positlon until the run 15 nearly ex 'mnded to its limit,

at which time a verv little outward are l theadjacent ends of thcsecjthmF-z 4: and 5 1' provide a dowel pin :26 on the plate 12 and tions with registering o 'ieninge to receive the dowel. I also provide a similar dowel 27 on the spring plate 6 to premnt relative lateral movement of the ends of the rim at this point.

I also provide a dowel 58 on the plate to retain the adj cent ends of the sec'liom; 3 and properly reg stored. he a further means of rigidly holding the adjacentends of the sections 3 and 5 registered, it rovide a dowel 29 on the toggle linl: ll 1m; enter a hole 30 in the Web of the rim This last dowel relieves the hinge joint 16 of most ing condition.

In Fig. (3 l. have shown the joint hbtween the sections 3 and'fi of the interlocking; form that is, provided with tongues 11 and recesses 10 as hereinheiore described.

As various structu vention will readily suggest themselves to one skilled in the art. I do not confine or limit my invention to the specific structures herein shown and dcswrihed.

I claim:

i. In a rim of the kind dem-rihcd a transverse cut in the rim and a plate within the rim for connecting the two ends thereof said out extendingti'ai'isversel3, through the web oi. the rim and radially part Way through the two flanges then extemfling cir cun'iicrentially of the rim in the flanges in opposite direction in the two flanges a mist tively short distance and then extending ra dially through the outer edges oi? the two flanges.

2. In a rim of the kind described out apart a one point in its circumference, the ends of the rim at the out being formed cn'ihodying my ink Illlll with circumferentially oppositely extending tongues and cooperating recesses at outer 'tially ing the other adjacent ends,

' other end to the shorter edges of theflanges of the rim, whereby the ends of the rim are interlocked radially in both directions, and a plate within the rim joining the two ends together.

3. A collapsible rim of the kind described, divided transversely at one point in its circumference by a cut extending transversely through the web of the rim and radially part way through the two flanges thereof, then extending circumferentially in one flange in one direction and circumfe'rem in the' other flange in the other direction, and then extending radially through the outer part of the two flanges from the ends of the circumferential )ortions thereby forming oppositely exten ing .Irnguesand cooperating recesses at the outer edges of the flanges of the rim, and a plate within the rim joining the two ends thus formed.

4. In a tire rim of the kind described, a rim divided into two sections, one longer than the other, a limited movement hinge joining. two adjacent ends and a link joinsaid link pivotally connected to the short section at a point adjacent, but beyond the end of the short section,

the longer section whereby'as section is swung within the longer section on said limited movement hinge, the limited movement hinge will permit the free inward movement of the shorter section a limited amount, after which the shorter section and the link act as a toggle lever adapted to forcibly flex inwardly the longer section through said limited movement hinge.

' 5. In a rim of the character described, divided into two sections, one. shorter than half a circle, the shorter section connected at one end to the adjacent! end of the longer section by a bridge plate within the rim, and loosely litting connectors joining the plate and the ends of the rim and permitting the shorter section to swing inwardly a limited distance, the adjacent ends of the sections at the hinged joint having radially interlo king projections and recesses.

In a tire rimofthe character described, said rim divided transversely at two points and pivotally connected at its" into sections, means linking the sections togcther at one point and adapted to allow the rim to collapse, a rigid bridge plate within therim at the other out and having its rim contacting surface formed on a less curvature than the inner face of the rim, and

connected to the run by loose connectors permitting limited hinging movement of the connected bridged ends of the rim.

7. In a collapsible tire rim of the kind described, the rmrcut apart at one point in its circumference, the out being zig-zagged in the two flanges of the rim and extending in opposite direction in said two flanges, thereby radially interlocking the two ends of the rim in both directions, a plate within the rim spanning said out and permanently joining the ends of the rim, said plate permitting a limited hinging movement only of the connected parts of the rim.

8. In a collapsible rim of the kind described, cut at a number of points; plates within the rim and joining the ends of the rim, the cuts having portions extending circumferentially in opposite directions in the two flanges of the rim and forming radially contacting shoulders, thereby radially interlocking the two adjacent ends of the'rim radially in both directions.

9. In a collapsible rim of the kind de scribed, out apart at a number of points, bridge plates within the rim and joining the ends of the parts, said cuts having portions extending in the flanges of the rim forming radially engaging shoulders, the ends of the rim provided witlrregistering notches in the web portion, and adowel )in von the bridge plate entering such note es and preventing relative lateral movement of the connected ends of the rim.

10. Ina collapsible rim of the kind described, said rim cut apart at least at two points in its circumference a rigid plate within the rim spanning the cut at one point, loose connectors joining the ends of the plate to the rim, the outer surface of the plate cut away toward its ends to permit a limited hinging ends of the rim at said cuts.

In witness whereof I hereunto subscribe my name this l th day of June, A. D., 1918.
